SPRING-SEAT SUHPOBT FOB CULTIVATOR-S.

To all whom it may concern.

Be it known that 1, JOHN '1. GAHAGAN, a citizen of the United States, residing at Normal, in the county of McLean and State of Illinois, have invented a new and useful Spring-Seat Support for Cultivators, of which the following is a specification.

The present invention relates to riding cultivators, and aims to provide novel means whereby the seat portion of a cultivator may be resiliently supported to enhance the riding qualities of the cultivator.

An important object of the invention is to provide a device of this character which may be readily and easily applied to a cultivator construction, eliminating the necessity of making alterations in the construction to apply the device.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the inven tion.

Referring to the drawings:

Figure 1 is a side elevational view disclosing the seat supporting beams as positioned on a spring device constructed in accordance with the invention.

Figure 2 is a fragmental plan view of the device.

Figure 3 is a plan view illustrating the invention as carried out for connection with a cultivator supplied with a continuous axle.

Figure 4 is an elevational view thereof.

Figure 5 is an elevational view of one of the U-shaped supporting members.

Figure 6 is a rear elevational view of a modified form of support, the seat supporting beams being shown in section.

Figure 7 is an enlarged detail view illustrating the means for securing the seat supporting beams.

Figure 8 is a modified form of the invention.

Figure 9 is a perspective view of one of the securing members.

Referring to the drawings in detail, the reference character 5 indicates an axle of a riding cultivator, which axle is formed with Application filed December 4, 1924. Serial No. 753,964.

a right angled end portion on which the wheel 6 is mounted, the opposite end of the axle being positioned between the members 7 of the usual cultivator frame.

Having connection with the members 7 are the side bars 8 that are secured to the mem bers '4', as by means of the bolts 9 that also pass through the axle to secure it to the frame.

Inverted U-shaped bolts 10 embrace portions of the axle there being provided a pair of these bolts 10 adjacent to the ends of the members 7. Plates indicated at 11 are secured by means of the inverted U-shaped bolts 10 which plates act as supports for the members 12, that are provided with offset portions 13 forming rests for the members 14: that provide abutments for the lower ends of the coiled springs 15, these coiled springs 15 support the saddles 16 that are curved to fit over the members 7 and have slots 17 that receive the beams 18 on which the seat 19 is mounted.

The forward ends of the beams 18 extend at angles and lie in parallel relation with the bars 8, to which they are bolted at 20 so that the beams 18 may move vertically, the bolts 20 acting as pivots.

From the foregoing it will be obvious that due to this construction, the beams 18 together with the seat may move vertically, the springs 15 cushioning the movements of the axle with respect to the beams to enhance the riding qualities of the cultivator. It might be further stated that nuts 21 are provided on the lower ends of the rods 22, which rods act as guides for the coiled springs 15, and at the same time hold the supporting plates and saddles in spaced relation with respect to each other.

The form of the invention as shown by Figures 3 and 4 of the drawings illustrates a construction especially adapted for utilizing applicants invention in connection with a cultivator wherein the axle is continuous, the axle being represented by the reference character 23. In this form of the invention the supports are indicated by the reference character 24 and are provided with right angled end portions 25 providing rests for the cups 26 in which the lower ends of the coiled springs 27 are positioned, the upper ends of the springs 27 being positioned in the cups 28 that engage the saddles 29, the

cups and springs being held in position by .414 Wmvr means of the bolts 30 and nuts 31 that extend through suitable openings formed in the supports and saddles.

The supports 24 are held in position on the axle, by means of the securing plates 32 which in turn are secured to the axle by means of the inverted U-bolts 33 that have their threaded ends passing through the plates 32 as clearly shown by Figure at of the drawings.

The bolts 30 are formed with oi'lset portions shown more clearly by Figure 5 of the drawings and indicated at 3a, which oti set portions provide supports for the rod 35 that acts as a foot rest for the operator of the cultivator. As shown by Figure 6 of the drawings, the axles which are indicated at 36 provide supports for the plates 3'? that are held against movement by means of the inverted U-shaped bolts 38 that overlie portions of the axles 36.

The supporting members that are disposed between the plates 37 and axles 36 are formed with openings to QCCOlIllIlOClZItQ the bolts 40 that act as guides for the coiled springs 41 which are shown as having their ends positioned in the cups 4C2. Hook mem-- bers 4-3 are formed on the upper ends of the bolts 40 and are designed to overlie portions of the seat beams 44 to hold the beams to the saddles 45, the beams being shown as positioned in suitable cutout portions formed in the saddles in a manner to prevent lateral movement of the beams. Spacing bars 35 hold the members 45 in spaced relation, the members 35 having openings 49" to accommodate the members a0 and permit of lateral adjustment of the members 4-5.

InFigure 8 the plate 39 is shown as provided with olljset portions 36 having openings to accommodate the bolts 40 that have their heads extending through suitable openings formed in the offset portions 46 of the members 45. Cups 42 are supported adjacent to the offset portions 36 and 46 and accommodate the ends of the coiled springs 41 to hold the springs in position against lateral movement.

The reference character 38 indicates an inverted U-shaped bolt that passes through suitable openings in the plate 39, which plate is held between the axle and the plate 37.

From the foregoing it will be obvious that due to the construction as shown and described, the usual seat supporting bars will be resiliently supported, in a manner to relieve the operator of the unusual jars and jolts incident to a cultivator passing over rough ground.

I claim 1. In combination with the axle and pivoted seat supporting beams of an agricultural machine, supporting members secured under the axle and having lateral oil'- set port-ions, spring members supported on the offset portion, saddles havin slots to ac commodate the seat supporting beams, said saddles having ofiset end portions adapted to engage the upper ends of the springs, and means; for securing the springs to the ollset portions of the supporting members and the saddles.

2. In combination with the axle and pivoted seat supporting beams of an agricultural machine, supporting members secured under the axle, saddles arranged above the axle and supported in spaced relation therewith, coiled springs mounted on the supporting members and having their upper ends engaging the saddles to support the saddles, said beams adapted to rest on the saddles, and means to prevent lateral movement oil the seat supporting beams.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

JOHN T. GAHAGAN.
